摘要 鹤峰县大典河滑石矿床位于走马-东山峰背斜南西段之南东翼,其赋矿层位为上震旦统-下寒武统灯影组二段。矿体空间形态呈似层状、透镜状大致与围岩整合产出,形态简单,边界规则。通过初步分析,矿床成因与地层、构造及动力变质作用有关,属于沉积-变质型矿床。本区与湖南省石门县清官渡滑石矿区相邻,均位于走马-东山峰背斜南东翼,两者赋矿层位相同,矿石质量特征也基本相似。在大典河-清官渡一带,灯影组地层分布广泛,走向断层发育,成矿地质条件优越,故沿赋矿层位寻找滑石矿潜力巨大,是今后找矿和勘查的工作重点。 Dadianhe talc deposit in Hefeng County is located in the south-east wing of the south-west section of Zouma-Dongshanfeng anticline,ore-hosting horizon is the second member of Dengying Formation of Upper Sinian to Lower Cambrian.Orebody spatial shape is layered and lenticular,which is integrated with surrounding rock.Through preliminary analysis,the genesis of the deposit is related to strata,structure and dynamic metamorphism,and belongs to sedimentary-metamorphic deposit.This area is adjacent to the Qingguandu talc mining area in Shimen County,Hunan Province,which is located in the south-east wing of Zouma-Dongshanfeng anticline.Both ore-hosting horizons are the same,and ore quality characteristics are basically similar.In the Dadianhe-Qingguandu area,Dengying Formation is widely distributed with faults and favorable geological conditions.Therefore,there is great potential to search for talc deposits along the ore-bearing horizon in the Dadianhe-Qingguandu area,and it will be the focus of future prospecting and exploration in the future.
